Talesun, formally Suzhou Talesun Solar Technologies, was founded in 2010 and is headquartered in Suzhou, Jiangsu province, China. The company has shipped more than 36 GW of modules cumulatively and, as of Q1 2025, appears on BloombergNEF's Tier 1 module maker list, reflecting recognition by mainstream global lenders and insurers. Between the two, Q-Cells carries the considerably stronger institutional footprint, backed by one of South Korea's largest conglomerates and a manufacturing presence spanning multiple continents. Q-Cells is broadly positioned as a premium-to-mid-range brand for residential rooftops and commercial installations across the US, Europe, and Australia. Its panels center on Q.ANTUM PERC-derived cell technology, and the company has confirmed active development of TOPCon and perovskite-silicon tandem modules, with a 28.6% efficiency record achieved on a tandem cell in late 2024. Current commercial models reach efficiencies around 22.5%, and independent reviewers single out the brand for strong temperature-coefficient performance in hot climates. Talesun covers a wider output range, from entry-level modules to high-wattage panels near 710 W, with efficiencies spanning roughly 17.5% to 23% depending on series. Its pricing is generally competitive, and the brand appears across residential, commercial, and utility-scale projects, particularly in Asia-Pacific and parts of Europe, though some independent reviews flag mixed field reliability compared to the top tier of competitors. For most buyers in 2025, Q-Cells is the more defensible default, offering broader installer familiarity, a stronger warranty track record, and the financial security of a major Korean conglomerate behind it. Talesun is a credible Tier 1 option for cost-sensitive commercial or utility projects where price per watt leads the decision, but buyers should seek independent field-performance data before committing it to long-duration residential installations. \---LINKS--- \- https://www.energysage.com/solar/best-solar-panels-complete-ranking/q-cells-solar-panels-complete-review/ \| Q CELLS Solar Panels: The Complete Review - EnergySage \| review \- https://www.solarreviews.com/blog/hanwha-q-cells-solar-panels-complete-review \| Expert Review of Qcells Solar Panels for 2025 - SolarReviews \| review \- https://8msolar.com/talesun-solar-panel-review/ \| Talesun Solar Panel Review - 8MSolar \| review \- https://www.pv-magazine.com/press-releases/talesun-aiming-10-gw-global-pv-module-capacity/ \| Talesun Aiming 10 GW Global PV Module Capacity - PV Magazine \| article \- https://taiyangnews.info/technology/qcells-to-invest-big-in-tandem-solar \| Q Cells To Invest Big In Tandem Solar - TaiyangNews \| article Written by claude-sonnet from the figures above. ## Other comparisons - [Q-Cells vs A.B.
